Eight delays hmmm let's see.
-Some standard clean pristine digital delay, with introducible modulation.
-Tape delay? For crazy oscillation fun.
-Filtered delay. Perhaps with both the high and lowpass filters? Lowpass could be used to emulate analog delays, but the added highpass would open up lots of options.
-Pattern or something of the type?
-Lofi/Bitcrushed.
-Pitchdelay. (shimmer I guess?) But perhaps where the pitch can be controlled via a foot controller or can be heavily modulated.
-Swell. I don't really use this but a lot of people seem to.
-Random or not random stutter delay, à la hold function on Boss pedals or Jonny G's infamous Max/MSP patch at the end of this video:
